Pancreatitis: Causes, Symptoms, Treatment, and Prevention

Pancreatitis is an inflammatory condition affecting the pancreas, the organ responsible for aiding digestion and regulating blood sugar. It may be acute (lasting for a short period) or chronic (persisting long-term), with treatment options varying based on the severity of the condition.

Types

There are two types of pancreatitis: acute, which develops suddenly, and chronic, which persists over time.

• Acute pancreatitis is an inflammation that lasts for a short time. There can be a range of symptoms from mild discomfort to a potentially life-threatening illness. Most people who have acute pancreatitis recover completely after getting the right treatment. In severe cases, acute pancreatitis can cause serious bleeding, serious tissue damage, infection, and cysts. Severe pancreatitis can also have serious consequences for other important organs, such as the heart, lungs, and kidneys.
• Chronic pancreatitis is a prolonged condition characterized by ongoing inflammation of the pancreas. It is most often seen after an episode of acute pancreatitis. Another big reason for health problems is drinking excessively for a long period of time. Pancreatic damage from high alcohol consumption may not cause symptoms for years, but then suddenly, severe pancreatitis symptoms may appear.

Causes and Risk Factors

Acute pancreatitis can result from several factors, including:

• Autoimmune diseases
• Drinking lots of alcohol
• Infections
• Metabolic disorders
• Gallstones
• Trauma
• Surgery

In some cases of acute pancreatitis, doctors cannot find the exact cause, which happens in up to 15% of people.

Causes of chronic pancreatitis include:

• Cystic fibrosis
• A family history of pancreatic disorders
• Gallstones
• High triglycerides
• Prolonged use of alcohol
• Medication

In 20% to 30% of cases, the cause of chronic pancreatitis is unknown. This condition most commonly affects men in their 30s and 40s.

Symptoms

The most common symptom of pancreatitis is pain in the upper abdomen. The pain can be severe, spread to the back, chest, or shoulders, and may feel worse after eating. The belly may feel tender, swollen, or sore.

Acute Pancreatitis Symptoms

• Severe upper belly pain
• Nausea and vomiting
• Fever
• Fast heartbeat
• Fast, shallow breathing or shortness of breath

Chronic Pancreatitis Symptoms

• Constant upper belly pain, often worse after eating
• Indigestion
• Loss of appetite and weight loss
• Diarrhoea
• Oily, smelly stools that may leave a film in the toilet
• Lightheadedness from low blood pressure
• Signs of diabetes, such as more thirst, hunger, and urination

Symptoms can look like other health problems, so medical advice is important.

Complications

Pancreatitis can have severe complications, including:

• Diabetes occurs when there is damage to the cells that produce insulin
• Pancreatic infection
• Renal failure
• Malnutrition occurs when your body cannot absorb enough nutrients from your food due to a deficiency in digestive enzymes.
• Pancreatic cancer
• Pancreatic necrosis
• Breathing problems occur when chemical changes in your body affect your lungs
• Pseudocysts occur when fluid collects in a blister. on the pancreas. They can become infected and burst.

Diagnosis

Doctors diagnose pancreatitis by checking your symptoms, medical history, and test results. They begin with a physical exam to look for pain or tenderness in your belly.

Blood Tests

Blood tests help check how your pancreas and other organs are working. Doctors look for high levels of pancreatic enzymes. Levels that are much higher than normal can suggest pancreatitis. Blood tests may also check your immune response, nutrition levels, fat-soluble vitamins, and blood sugar to see how well your pancreas makes insulin.

Imaging Tests

Imaging tests create pictures of the inside of your body. These tests can show swelling, inflammation, fluid buildup, gallstones, blockages, or other changes in the pancreas and nearby organs.

Common imaging tests include:

• Ultrasound: Uses sound waves to look at organs in the belly and check blood flow.
• CT scan: Shows detailed images of the pancreas and the extent of inflammation.
• MRI and MRCP: Show detailed images of the pancreas, gallbladder, and bile ducts.
• Abdominal X-ray: Creates images of tissues, bones, and organs in the belly.

Endoscopic Tests

Some tests use a thin, flexible tube placed through the mouth to look inside the digestive system.

• Endoscopic ultrasound (EUS): Shows inflammation, gallstones, tumors, or duct blockages.
• ERCP (endoscopic retrograde cholangiopancreatography): Uses a scope and X-rays to examine the bile and pancreatic ducts and find problems.

Stool and Pancreatic Function Tests

Stool tests can check for excess fat, which may mean your body is not absorbing nutrients well. Other tests measure how well your pancreas makes digestive enzymes. Doctors may collect fluid from the pancreas during an endoscopy to test its function.

Your doctor may choose different tests based on your symptoms and health condition.

Treatment

Treatment depends on the cause and how severe the condition is. Most people need hospital care, especially with sudden attacks.

Acute Pancreatitis

The pancreas needs rest and support to heal. Treatment may include:

• Pain relief medicines
• IV fluids to prevent dehydration
• Nutrition support, such as a feeding tube if you cannot eat

If gallstones are the cause, doctors may remove them using ERCP or perform surgery to remove the gallbladder. Complications may require antibiotics, procedures to drain fluid, or intensive care.

Chronic Pancreatitis

Long-term care focuses on reducing pain and helping digestion.

• Stop drinking alcohol and stop smoking
• Take pain medicines or have procedures to manage pain
• Use pancreatic enzyme supplements to help digest food
• Take insulin if diabetes develops
• Follow a low-fat, nutrient-rich diet

Some people may need endoscopic procedures or surgery to remove blockages, drain fluid, or remove damaged parts of the pancreas.

Prevention

There is not always a way to prevent pancreatitis, depending on the cause. With that said, there are several things you can do to reduce your risk:

• Limit alcohol use
• Stop smoking
• Maintains moderate weight
• Eat a balanced diet
• Eating high-fiber foods and avoiding sugar may help prevent diabetes and gallbladder fluid, which is the main cause of acute pancreatitis.
